DHCP : Java Glossary

DHCP (Dynamic Host Configuration Protocol)
is a technique used in W95, W98, Me, NT, W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32 and W10-64
for dynamically assigning IP (Internet Protocol) numbers. A DHCP
server assigns IP
numbers for a temporary period. They also automatically assign some DNS servers, telling you the IP
to use. The magic of DHCP is that workstations don’t need to know the
IP of the
DHCP server to get started. PPP has a similar mechanism to dynamically assign
IP numbers for dial
up calls. DHCP is commonly used for 24/7 cable modem access.
DHCP is primarily for convenience rather than to allow
IP
to change frequently. With DHCP, nobody has to assign numbers to individual
workstations and configure them individually. All machines are set to
DHCPIP
assignment. They automatically find themselves a free IP
when they are turned on, with the help of a DHCP
server. The secondary reason for using DHCP
is to make maximal use of a small pool of
IP numbers when you
have more users than IP
available.

DHCP servers in my experience tend to be somewhat flaky.
You can cheat and set the IP it keeps giving you as a permanent
IP. If you
don’t use DHCP, you must also manually configure some
DNS (Domain Name Service) server IPs. If anything goes wrong, revert to
DHCP, reboot and pray the DHCP
servers are up.

You can also clear its pea brain with:

When you have a router you can use static or DHCPIP
assignment for for your computers to talk to the router and also for the router to talk to
your IAP (Internet Access Provider).

IPCONFIG /release
IPCONFIG /renew

You then have configure the DHCPs (Dynamic Host Configuration Protocols) in your various computers attached to the LAN (Local Area Network) and for the the DHCP in the router.

Alternate DNS Servers

Your DNS servers may have the wrong IP or may not have the domain you want on file. If your ISP is not providing reliable DNS servers, or you suspect there is a
problem with them you can try out some alternates. Of course, these alternates may fail too, so don’t forget how to put them back the way they were. Since your ISPs servers are physically
close, they should provide the fastest service. To configure DNS servers, Click Control Panel ⇒ Network & Internet ⇒ Network Connections ⇒ right click Properties.

Google DNS Servers: 8.8.8.8 and 8.8.4.4

IsItDown DNS servers: 208.67.222.222 and 208.67.220.220

It might be wise to write down your current
ISP-supplied DNS servers so you can manually force their use if DHCP stops working.

You might want to mix servers from two different sources so it will continue to work even if one source goes down.
